Sensitivity encoding, also known as parallel imaging, is a technique used in magnetic resonance imaging (MRI) to accelerate image acquisition by acquiring multiple sets of data simultaneously. This method takes advantage of the fact that different coil elements in an MRI system have different sensitivities to the signal from the imaged tissue, allowing for increased efficiency in data acquisition. By utilizing multiple receiving coils instead of a single coil, sensitivity encoding can reduce the acquisition time of an MRI scan, making it particularly useful for patients who have difficulty holding still for long periods or for imaging moving organs. This technique has been shown to improve image quality while reducing artifacts caused by motion or other factors. Overall, sensitivity encoding is a valuable tool in MRI imaging that allows for faster and more efficient acquisition of high-quality images, ultimately benefiting both patients and healthcare providers.
